SPECIFICATION forming part of Letters Patent N o. 546,775, datedSeptember 24, 1895. Application liled April 2, 1895. Serial No. 544,168.(No model.)

To all whom it may concern:

Be it known that I, EDWIN G. EMMERT, a citizen of the United States,residing at Sherdahl, in the county of Republic and State of Kansas,have invented certain new and useful Improvements in RailroadCattle-Guards;

and I do declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

The special object of the invention is to makea cattle-guard gate whichmay be automatically opened by each train as it appreaches.

Figure 1 of the drawings is a-plan and Fig. 2 a perspective view of myinvention, showing it applied.

In the drawings, A A represent the rails of a railway, under and betweenwhich is secured the board or plate B, from which, at one corner,uprises a post C. To the latter is hinged a gate D, extending across thetrack to prevent stock from passing out of a fenced field.

E is a crank-shaft pivoted to turn in postbearings c c and connected byan eye e at its outer end with adouble hook F, the latter beingconnected with an eye-rod G, made fast tothe gate-stile ol. The gate isheldin position across the tracks by a coiled spring H, one of whoseends is secured to the gate-'stile d, while the other is coiled aboutthe staple I, or any other suitable contrivance. When the force whichopens the gate has ceased to operate, the tension of the spring willclose it.

J is a pinion fast on the lower end of the crank-shaft E and meshingwith a spur-wheel K, which turns on a pivot in the board or plate B. Onthis spur-wheel is a fixed arm It, which extends under the track A', andon this arm is middle-riveted a plate L, with a hole Z near each end. Ineach of the holes l is secured one end of a rod M, whose other end ispivoted to the lower end of a lever N, whose upper end is struck by thewheel of each car on that side of the tracks, so as to operate the trainof mechanism described and open the gate. The latter is thus held openuntil all the train has passed, when the coil-spring reti-acts the gateinto position across the track. I may support thc rod M in a pivotedhanger o, but, while preferable, that is not necessary.

I am aware that cam-blocks, vibrating carnlevers, springs, and chainsover pulleys are not new in connection with hingedY railroadgates; but

What I claim as new is The combination of a post C, a gate D hingedthereto and extending across the track; a shaft E supported in bearingson the post which carries a pinion J and hasa crank-arm extending behindsaid post; an arm G secured to the gate-stile; a link F connecting arm Gwiththe crank-arm; a spurwheel K intermeshing with the pinion .I andhaving an arm which passes under and completely across the track,tread-levers N connected to said arm; and a retracting spring secured tothe gate, all substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
